Hi Herman, you're right. Btw, I have use extensively the ffmpeg (libswscale) for packed yuv422 -> planar yuv420 and also for resizing. It's correct and works fast. For other conversions we might test them, especially for SD RGB -> YUV and HD RGB -> YUV (remember the color primaries are different for SD and HD). Also 444 <-> 422 <-> 420...
I remember of some issues related to converting interlaced to progressive material.
